Facing issue while pushing data into Event hub via Telco Generator

Hello,

I was trying to implement the sample provided for Stream Analytics using Event hub. But I am facing issue while I am trying to push the data into Event hub. I have used sample code provided for Telco generator.  Error I am getting is as :A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

and stack trace is as:

Server stack trace:

I have provided correct  Event hub name and correct connection string as:

Endpoint=sb://<namespacename>.servicebus.windows.net/;SharedAccessKeyName=<sharedaccesskeyname>;SharedAccessKey=<accesskey>;

Earlier I thought it is a network related issue and proxy server is restricting me to access it via .NET application hence I have added following lines in config file, yet I am facing issue:

<system.net>
    <defaultProxy useDefaultCredentials="true">
      <proxy proxyaddress="http://proxyserverurl:port" bypassonlocal="True"/>
    </defaultProxy>
  </system.net>

I have tried all the combination for this but no luck. how will I resolve this issue

Thanks, Manthan Upadhyay
